People have argued this but Google has made it clear why they won’t charge - that is their moat. By pricing the service as free, they price out all competing services by making it so that all creators, new and old, will use YouTube by default. Especially with new creators, with no startup cost and a huge audience, there is no reason for to use any service that requires payment. This effectively tanks all competitors and is why the only surviving competing streaming services target niche audiences. For example, established creators who have the sway to bring an audience with them.
